1. The problem statement, all variables and given/known data For what values of k does the function f(x)= x^3 + 6x^2 +kx -4 give the same remainder when divided by x-1 and x+2? answer, however in the booklet it says the answer is 3, why is this? what did i do wrong? 2. Relevant equations 3. The attempt at a solution So.. i set up two equations one using f(1) and one using f(-2) f(1)= 1 + 6 + 1k -4 f(1) = -2 +k 2 = k f(-2) = 12 -2k 2k = 12 k= 6, I plugged 6 and 2 into the equation of f(1) and got the same (remainder of 9) wat am i doing wrong?
